By VIP, I mean Big or Birdo. You might get mail from them saying that they'll be at a certain Dream event cheering you on. If you spot them there, press '(-)' for a bonus 100 stars and their suit.
If you still don't get it, you might get mail from Birdo saying that she'll be at the Dream Curling event cheering you on. She could be on the side of the alley, or by the ice statue penguins at the top of the alley. Something like that.
|Big Suit||Spot Big at the specified Dream event and press '(-)'|
|Birdo Suit||Spot Birdo at the specified Dream event and press '(-)'|
